Hi Paul, is this a fresh install of Lubuntu, or an upgrade?  I have
found that sometimes config files can cause problems like these, though
alot of this is speculation at this point.  So, to better assit you, I
would like to know more about your setp.
Do you have other DE installed beside LXDE(Lubuntu), like Gnome, Xfce, etc?
Can you also tell us more about your computer?  What type of graphics
card is installed? (Intel, Radeon, Nvidia???)  What type processor do
you have (32bit, 64 bit)?
will print out some info, look for your VGA controller (lspci | grep
VGA      will also work)
uname -a
will list the processor info.

Are you using the open source graphics driver for your computer, or did
you install an additional driver for it?

Have you successfully run a different version of Lubuntu on it?

It looks like an X problem, so it could be a simple

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
(backup the old config file first)

sudo dpkg-reconfigure xserver-xorg
(reconfigure X)

You should try logging into a guest account to see if it is a config
file for your account that is messed up.
If you can log in as a guest and everything work fine, it is a config file.

Since I don't know which config files are specific to X off the top of
my head,  backup your entire config directory and delete the old one.
(Unless someone can chime in with the exact config file/directory....
This is potentially dangerous if you mistakenly enter it incorrectly, so
ALWAYS use caution with the rm command.  You can do this from within
PCManFM just as easily, though you need to show all the hidden files to
do it.  Simply create a .backup_config/ directory and copy your
.config/  directory into it and then delete the .config/ directory.

>From the terminal:

cp -R  ~/.config ~/.backup-config

rm -R ~./config
(delete the everything in the config directory)

Then you can move things over 1 by one (like mozilla/ so all of your
bookmarks are back)
